The general structure of the submarine has been completed, then the next step is optimization. In this regard, only Chi Nan can do it himself, and so far, no one has been able to complete it.

Olna finally had time to take over her airship formation. After explaining everything, she returned to her job. For work, the enthusiasm shown by Weisi made Chi Nandu feel helpless. Compared with these women, I am not too lazy. No, no, I'm a scientist.

Chi Nan thought in his heart while continuing to improve. Nowadays, although submarines only have such a means of attack, they are also submarines after all, and it is enough to fight in the water, and you can't expect too much.

The sea, land and air gathered, and their plans finally completed the last shortcoming.

Milia surrounds Chi Nan every day, staring at Chi Nan without blinking. Because of the reasons to be studied, Silinka also gave up continuing to toss Chinan, just by the sea as if on vacation.

All in all, as long as there is enough food for this little gluttonous cat, there is no problem.

"Why have you been here, what's the point of studying submarines, you don't. ”

Chi Nan understood that the research on submarines probably relied on Orna, and Miria had no other role except jumping around. It's the same now, and the opinions are all inexplicable.

"Of course I'm looking at the submarine, you hurry up and get it out, I'm the future submarine commander-in-chief." ”

"You just want to go out into the sea, and it's dark down there. ”

"What does it matter, don't we have lights on our submarines. The sea is so interesting, and it's all things that you don't have on land. I'm looking forward to seeing more things in the sea that I've never seen before. ”

This curiosity simply broke through the sky, Chi Nan rolled his eyelids and continued to study. But at this time, Chi Nan suddenly stopped. "What's wrong, what's wrong, how did you stop, are you angry. ”

Although Miria said this, she was not afraid at all. This guy Chi Nan simply has no temper to his own people, as long as he is familiar with it, no one around him will think that Chi Nan is not good to talk to.

If it weren't for the fact that Chi Nan was a lord, I'm afraid many people would kick their noses in the face.

Chi Nan took a plant brain crystal plate from the side, and the crystal plate instantly lit up. "An enemy is coming. ”

Chi Nan said a word, and all the people around him were immediately attracted to it. "Don't squeeze it, pick up the crystal plate, and I'll send you the image. "Not only the people around me, but also people from afar.

In the information age, the transmission speed is so fast, almost instantly, everyone in the entire territory who is qualified to know about this matter knows. The image of the hedron slab shows some black dots in the distance approaching this direction.

After zooming in on the image, Chi Nan found that these black spots were actually some boats. "This is the Flying Boat, from the Holy Dragon Empire. It doesn't have the logo of the Holy Dragon Empire on it, but it is definitely the flying boat of the Holy Dragon Empire. Without waiting for Chi Nan to say anything, Silinka Ye next to her spoke first.

"What's going on? You know?"

Silinka nodded lightly: "Of course, although the Half-Elf Empire rarely communicates with the outside world, the three major empires will hold a secret competition every year, on the one hand, to show their strength, and on the other hand, they also want to see the gap between themselves and other empires, so as to determine the next direction of development." ”

"Aren't there four empires, how to compete there are only three empires. Miria said curiously.

Silinka Ye explained indifferently: "Among the four empires, the half-elf empire is dominated by half-elves, and half-elves are mainly of human and half-elf blood. Both the Holy Light Empire and the Holy Dragon Empire are dominated by humans. Only the Evil God Empire is different, those people can no longer be regarded as people. Both the Evil God Empire and the Plains of the Dead are public enemies of all races on the continent. ”

Now everyone understands that since they are public enemies, how can they hold a competition with them. In war, there is almost always a fight. The Half-Elven Empire has been fighting elves against the erosion of the Plains of the Undead.

On the Evil God Empire's side, it has been fighting against the Holy Light Empire. Only the Holy Dragon Empire is relatively peaceful, usually supporting the Holy Light Empire, and more often than not, there is nothing to do.

"Don't talk about these things yet, what kind of flying boat is this?" Chi Nan keenly found the problem.

Silinka glanced at Chi Nan deeply: "This is the latest model, and its strength and size are stronger than other flying boats. And the defensive barrier should have been adjusted. With the previous airship, I'm afraid it's not an opponent. ”

Chi Nan also understands that after all, those models that have been eliminated, their own airships are not opponents, and in the case of conflicts on the battlefield, when the number of opponents is small, their losses are nearly doubled, and now it is even worse.

"Chi Nan, let me come, since our third-generation airship has been built, let's take it out and try it. These flying boats did not have the emblem of the Holy Dragon Empire on them, indicating that they did not dare to attack blatantly. Orna said suddenly.

Silinka Ye agrees: "That's right, if you have something good, take it out and use it." Rest assured, we are here, as long as we condemn in the name of the Half-Elf Empire, they will definitely not dare to come to you for trouble. If you want to make excuses, why should it be a few years later, don't you need time the most? ”

Hearing Silinka Ye say this, Chi Nan was relieved: "Then I'll trouble you." However, it is better not to let the Holy Dragon Empire find out. New formations have also appeared, bypassing from behind, not allowing them to escape. ”

Chi Nan quickly calculated the number on the screen: "The number of the other party is close to two hundred, and we have one hundred and twenty-four ships in one formation, although the number is insufficient, but I believe that our strength is definitely stronger." Stay safe, Olna, I'll leave it to you. ”

Chi Nan plans to use an airship formation to fight against the other party, but now the airships have been simplified by Chi Nan. The strength increases, but it is actually easier to manufacture and assemble. As the energy pool increases, so does the speed at which airship formations can be built.

"Don't worry, we'll leave the rest to us, as long as there's no problem with your airship. ”

Whenever there is a fight, Olna's words become more and more. Well, there seems to be something wrong with what I'm focusing on. At this moment, the officials of a certain status in the entire territory switched the screen to the fleets of both sides.

The people of the Holy Dragon Empire didn't know that they had already been discovered before they reached the coastline of the Holy Tree Territory.
